LUBRICATOR.

Specification of Letters Patent.

Patented March 19, 1907;

Application filed August 31,1906. Serial No. 332,734.

To all whom, t may concern:

Be it known that I, JOHN WILLIAM HINOH- oLIFF, a citizen of the United States, and a resident of Jackson, in the county of Hinds and State of Mississippi, have invented a new and Improved Lubricator, of which the following is a full, clear, and exact description.

My invention relates to lubricators adapted to be applied to j ournal-bearings in general, and to armature-bearings for street-railway motors in particular. The j ournal-bearings of such motor armatures and cars are now lubricated with grease which does not operate until the bearings have become heated by friction. Such friction entails a considerable loss of power and causes the bearings to become worn in a short time.

My invention has for its object, therefore, to provide a lubricating device simple in construction, eective and economical in operation, and durable in use. This I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which- Figure 1 is a side elevation of a device embodying my invention applied to a ournalbearing, shown in cross section with the housing partly broken away. Fig. 2 is a side elevation of my device applied to a journalbearing, shown in cross-section. Fig. 8 is a central vertical section of the parts shown in Fig. 2. Fig. i is a plan view of the device shown in Fig. 2, and Fig. 5 is a horizontal section taken on the line 5 5 of Fig. 3.

`As illustrated in the drawings, A represents a housing of any suitable construction, in which is arranged a car-axle I-I, having a j ournal-bearing G mounted thereon and arranged within a bearing-box I. A cap B may be hinged to the housing A and adapted to be turned upward.

D represents an outer tube provided on its lower end with an exterior thread adapted to engage a corresponding interior thread formed on the bearing-box G. This tube is provided with an aperture d, which preferably flares inwardly, making a contracted opening on the outside and a wide opening on the inside of the tube. This aperture is located at a point near the bottom of the oilchamber hereinafter referred to. A tube F is arranged within the tube D and is provided with apertures f. The upper and lower ends of the tube F are preferably open, and the lower end is surrounded with a body of felt which extends also around the outer surface of the tube. An outer shell O inclosesvthe tube Dand is provided with perforations c, thereby forming a screen, which may be made of wire-gauze or other suitable construction.

When the device is applied to a journalbearing, it is arranged within a chamberor well similar to those now used for holding grease, and such chamber is filled with a lubricating-oil. This oil passes through the perforations c of the screen O and through the aperture d of the tube D and into the felt E, which surrounds the inner tube F. The felt takes up and retains the lubricating-oil and applies the same to the journal-bearing. The outer screen O prevents sand, dust, dirt, and other foreign matter from reaching the aperture d and coming in contact with the felt. The apertures in the inner tube F facilitate the distribution of oil on the felt in starting up the motor in the morning or after filling the oil-box. The tube D may be provided with more than one aperture for allowing oil to pass to the felt surrounding the inner tube, if desired, and apertures having a uniform diameter may be used instead of the Haring aperture d without departing from my invention. I prefer the construction shown and described, however, for the reason that such Haring aperture permits the lubricating-oil under all conditions to readily pass into the felt and be absorbed thereby and prevents the aperture from becoming clogged.

Having thus described my invention, what `I claim as new, and desire to secure by Letters Patent, is-

1. In a lubricator, the combination with an inner tube provided with lateral perforations, of a body of felt surrounding the sides and lower end of said tube, an outer tube inclosing said felt and provided with a lateral aperture and a threaded endadapted to be secured to a journal-bearing, substantially as shown and described.

2. In a lubricator, the combination with an inner tube having open ends and provided with perforations, of a body of felt covering the perforations and lower end of said tube, an outer tube having an aperture and provided on its lower end with a thread, and an' outer foraminated shell adapted to serve as a strainer, substantially as shown and described.

3. In a lubricator, the combination With an inner perforated tube having open ends, of a layer of felt covering the sides and lower end of said tube, an outer tube provided with an aperture flaring inwardly and adapted to be located at a point near the bottom of an oil-chamber, substantially as shown and described.

4. In a lubiicator, the combination with a perforated inner` tube having open ends, of a layer of felt bearing against the perforated portion and the lower end of said tube, and adapted to be located at a point near the bottorn of an oil-chamber, substantially as shown 1 5 and described.

5. In a lubricator, the combination with an inner tube having an open lower end, of a layer of felt surrounding the lower portion. and end of said tube, and an outer tube i11- closing` said felt and provided ith an aperture Haring inwardly and adapted to be located at a point near the bottoni of an oilcliainber, substantially' as shown and described.

In testimony whereof I have signed my naine to this specification in the presence of tWo subscribing witnesses.
